Anytime you post something in Craigslist you are open to this kind of Scam. Here's the usual modus operandi:

You are the seler

1. Response to your advertisement.
2. Email back and forth. They say their representative/secretary/relative in the USA will send you payments.
3. They send you a check for more than what was originally agreed upon. They say take xxx amount for your trouble but refund (via wire transfer) them the remaining money.

Ex Cost of what you are selling is 1000 dollars
They send you 3500 dollars
They will ask you to cash the check, take 300 dollars for your troubles but send them/advance them 1200.
4. Your bank will make the 3500 available to you. You wire them 1200.
5. A few days later your bank calls you and informs you the check is no good. You are now out of 1200.

You are the buyer - This is easy to spot since most of the time, the same advertisement is plastered in different craigslist cities.
1. You email them about the item they are selling.
2. They said it's available. However, he is out of country right now but, lo and behold, he has a solution for this problem.
3. They will suggest to use a shipper company; in one of my bait, they suggested TNT.
4. Same deal with above, take xxx amount for your trouble, but wire them the rest.
